Cannot connect Bluetooth headphones in Dual Channel SBC XQ
Hello and thank you for the progress on this modern alternative to pulseaudio and jack. . I am posting this issue as a follow up on the below exchange some time ago, after trying several builds over time:
I installed pipewire on a fresh manjaro VM, as a test bed before transitioning from a forked version of pulseaudio (using pali's enhancements) from all my machines.
Did the required configuration (including setting bluez5.sbc-xq-support=true). My Bose 700 do connect in Joint Stereo however NOT in dual channel, not with the highest quality SBC XQ setting.
The same headphones are connected to the same dongle in SBC XQ Dual Channel using other software (bluez-alsa, pali's pulseaudio on manjaro, and also zenwalk) so it is not a hardware issue.
To help with diagnosing the problem I have just compiled the following files:
Attached file capabilitiesBose.txt is BTmon showing the Dual Channel capability is advertised by the headphones, and the successful SBC Dual Channel connection with other software solutions.
Attached file pwdump.txt is a pipewire dump.
Attached file journalctlentries.txt is a couple of easier to read logs (grep a2dp and grep blue).
Attached file failedDual-BTmon.txt shows the current bluetooth negotiation.
Attached file configs.txt shows the pipewire conf files.
Attached pwinfoall.txt shows the output of pw-cli.
Specs and software versions:

As @pvir mentionned he can successfully use his headphones in Dual Channel mode, I am hoping this can be done as well with the Bose headphones, and would appreciate any guidance. Thank you.
